citizen of the Unitid States, residing in the. city and county of SanFrancisco and: State of California, have invented new and use-;

'. ful Improvements in Devices for Inki'ng and. Dampening Printin-Ribbons, ofwhich the-following isaspeci cation; This invention relatesto means-.-fcr neinking and mpening ribbons-of duplicateprinting'machines;

The object of the present inventionisha provide a simple, practicableimplement whereby ribbons or webs ofthe. ty e used inzconjunction'. withduplicate pfintmgg ma chines may be re-inked by replenishing the.

" ink substances, or may have theiniiuseful providemeans whereby theslack. portions .ing thrcughthe implement, and means are life extendedby the addition. of a fluid,,on instance-water or dampening a dry' ordepleted ribbon..-

It is also an object 'of the invention to of .a ribbonmay'be drawn tautwhile. passalso provided for regulating; the tension at which the ribbonis drawn through the machine. Means are-alsoprovided and l adapted foradjustment whereby the I proper amount of'ink or moistening liquid canbe ap lied in the ribbon.

he invention consists of a suitable re? ceptacle with an immersiblecylinder with winding means,.apressure device, a take-up device, andtensicningelements.

"Inmounting. the reel 21-its recess end which is drawn during the windingoperation, between the pressure roller 11 and the liquid conveyingcylinder 4, so that a poron the-cylinder will betransposed to theribbon. Manifestly the ribbon is delivered from a reel 21* which issubstantially similar in construction and op tion of the liquid erationto the reel 21, and is mounted on the opposite side of the apparatus onsupports] 24-and 26. a

Afterthe ribbon to be treated is arranged 'byeonnection between thereceiving =reel"'21 and the delivery reel 21 crossing the upper portionof the cylinder 4, then the soft pressure roller 11 is adjusted in thepanels 6 and forces the ribbon20 downwardly u on the cylinder 4 withsufficient pressure,w en

it may be locked by the bolts 14. In order to compensate forirregularities in the area or length of one or the otherlongitudinalsides' of the ribbon 20, such irregularities being causedfrequently' by the much greater'use of one side of the ribbon than theother, which use causes that particular side to be stretched more thanthe other side, and in order to take out this slacknessof the ribbon Iemploy'a pair of adj ustabl'e guide rollers 29, which are mountedsomewhat'above the cylinder 4; the ends of the rollers 29 beingsupported in adjustable bearings 30, Fig. 6, mounted in the panels.

6 and provided with screws 31 whereby the elevation of the bearings canbe' controlled.

If, when the ribbon 20 is arranged between the reels 21 and 21, it isobserved that one side is slack," then the take-up rollers 29 can beadjusted higher atone and than the other by moving the bearings 30 byturning the screws 31; this adjustment of the take-up rollers 29 beingdesigned to draw the ribbon 20 substantially taut between the reels 21and 21?; the position of the rollers 29 being such .thatthe ribbonisdrawn up against the-lower half, approx:

h'nately, of the-pressure roller 11.

l. he operation of the apparatus is as. follows: Having placed thedesired fluid 'in the reservoir 3, and having arranged the rilihon- ZOso that iteonneets the reels 21 and 21 and resting onthe take-up rollers2!), then the soft squeezing or pressure roller 11 is adjusted with thedesired pressure upon the ribbon 20, so that this is. forced down intocontact with the eylinder 4. By turning thecrank 25 the couplerdevice'23 will drive the receiving reel 21 to ,unwind the ribbonfrom-the delivery reel '21; this drawing the ribbon 'over thetake- .upadjustable rollers 29 beneath the pressure roller 11 andcausing it tobear upon the surface of the fluid conveying cylinder- 4,.which beingrevolved by. the frictional engagement with the traveling ribbon willribbon. If it'is desired to apply a considerable quantity of liquid tothe ribbon 20,

lightly against the cylinder 4, thus permitting the ribbon to carry awaythe desired quantity of liquid;.or, if it is desiredto only slightlymoisten or impart'a small.

the pressure of the pressure roller 11 is increased, so that instead ofthe ribbon carrying a considerable quantity, the substance is' squeezedout of the ribbon 20 before it passes on the :ribbon between. thepressure roller 11 and the feeding cylinder 4. 'From thisit will beseenthat I am enabled to take a substantially used-up iribbon and renewits-usefulness by moisteningor by the -ap-' plication-pf an ink or otherfluid, and I can adjust the apparatus so as to determine the quantity ofmoisture or ink transposed totheribbon. In order to control the tensionof the ribbon 20, as it is drawn from one reel to another, I provideadjacent the support-' ing' shafts 24, friction blocks 24' which areadapted to bear upon the shafts 24; .the blocks being subjected topressure from. set:

screws 24. By this means, if it is desired to place the ribbon 20 underconsiderable tension I simply turn the set-screws 24' so as to force thefriction blocks 24' in'the end walls of the receptacle down upon theadjacent portions of the driving shafts 24.

In Figs. 9 and 10 I have shown a detachable'bearing'or bracket 32, whichmay be clamped to the wall of the receptacle 2 by a set screw 33; thebracket 32 being used to support one end of a reel, as 21, when this isof'a length shorter than the distance between the supports 24 and 26,Fig. 7; i

' Having thus described my invention, what I claim and desire to secureby Letters Pat ent,is- 1.
